Mary, you don't know how much you mean to me
If you did, you'd never ever make me feel this way
Mary, you don't know how much you care for me
If you did, I'd know you wouldn't make me hurt this way

Now I realize you may not feel the same for me
or are you trying to hide how much you care
Have you thought about how hard this is for me
To live in this one-sided love affair

Mary, you don't know how much I feel for you
If you did, I know you wouldn't hurt me this way
For you have to know I care, baby
Cause everything I've ever said or done
Should let you know that you're the one

Now you have to know you're more than just a friend to me
are you using me or are you just gone aware
Mary, can't you see that this is hard for me
To live in one-sided love affair

Now you know that in your heart
You feel the same baby
You're just trying to hide how much you care
Oh, let me in your heart or just let me be
But put an end to this one-sided love affair
